SIEECIFICATION forming part of Letters Patent No. 747,774, datedDecember 22, 1903. Application filed J nly 8, 1903. Serial No. 164,644.(No model.)

To eY/ZZ whom it may concern:

Be it known that LISAAC BELL RITTER, a citizen of the UnitedStates,residing at Philadelphia, in the county of Philadelphia vandState of Pennsylvania, have invented certain new and useful Improvementsin Switches, of which the following| is a s'peciiication.

My invention relates to improvements in railway-switches, and isparticularly adapted to street-railways where a central slot between thetracks is used for the depending plow carried by the cars to enter andmake contact with electrical conductors or' to en- Y gage a cable.

The object of my invention is to provide a switch mechanism which willcontrol the switch-tongues and the slot switch-bars in the central slot,giving them a positive and simultaneous-movement and locking the same ineither position-that is to say,l when the switch is opened or closed. v

My invention is provided with and operated by a pin located between thetracks, which is actedupon by an automatic switch-controller carried bythe car,such as that shown and described Ain Letters Patent for.Automatic switch-controller,. No. 692,050, dated 'the 28th day ofJanuary, A. D. 1902.

A further object ofmy invention is to have the above-mentionedoperating-pin concealed except when in operation. This is accomplishedby the operatingpin being raised above the surface of the street by thewheel of an approaching car depressing a piu in the rail, and after theautomatic switch-controlier on the car shifts the switch to the desiredposition the car-wheel depresses a seo-v ond pin, which causes theoperating-pin to disappear.

A still further object of my invention is to provide a means of shiftingthe switch by a car coming from the opposite direction from where thecentral operating-pin is located. This consists of two pins, one in themain track and one in the branch track, and as the car approachestheswitch the wheels will contact with the pin in that particular trackand-open the switch, so that the car may pass through it.

Referring to the drawings, Figure 1 illustrates a plan view of aswitch', showing my ings c.

invention embodiedtherein. Fig. 2 is a side view of the same. Fig. '3 isa vertical sectional view on line 3 3, Fig. 1. Fig. 4 is a verticalsectional view on line 4 A4, Fig. 1.

Fig. 5 is a view similar to Fig. 4,.showing the In the drawings, A and Arepresent the I tracks on theY mainline, and A2 and A3 represent thebranch tracks.

A4 represents the switch-tongues, pivoted at ai.

. B represents the central groove for the vplow carried by the car; B',the groove for the branch. track.

B2 represents plates covering the space between the tracks and centralgrooves to protect-the operating mechanism. f

B3 andB4 are the slot switch-bars, pivoted at b to the frame W.

The vertical shafts C and C', as shown in Figs. l ando, lare'adapted torotate in bear- On the shafts C and C are arms C2, to which are pivotedthe links C3 at c', and at c2 the said links are pivoted to theswitchtongues A4. The said arms also have links C4 pivoted to th'em atc3, which said links are pivoted to the slot switch-bars B3 and B4 at.c4.

The ,links C4are provided with extensions, forming hooks C5, whichengage the vertical shafts and prevent the shafts and-links from turningtoo far. In Fig, 1 shaft C is shown engaged by the hook C5, in whichposition the pivotpoints c, c2, c3, and c1 are all in line with thevertical shaft C', forming a deadcenter and locking the switch-tongue A4and the slot switch-bar B4, so that they cannot be moved by any forceapplied directly to them.

The vertical shafts Cand C are rotated by' thefollowing means: Eachiis-provided with an arm C6, and pivoted to said arms are the rods C7and C8, as, shownV in Fig. 6., .The said rods are pivoted at theiropposite ends to a lever C9, which is pivoted vto and carried by thelever C10, which is secured at C11 to the rock-shaft C12. It will'readily be seen that by rotating the said rock-shaft C12 the verticalshafts will be turned and operate the switchtongues and the slotswitch-bars.

As shown in Fig. l, the vertical shaft C is locked by the links; but theshaft C is not locked. To hold the shaft C in its proper position,aweight C43 is provided which acts upon the rock-shaft C12. The weight iscarried by an arm C14, pivoted to the frame W. (See Fig. 6.) A link C15connects the weight-arm and the lever C10 upon the rock-shaft C12 andholds said rock-shaft in its proper position. When the rock-shaft C12 isrotated in the direction of the arrow, the level' C40 raises the weight,and when said lever C10 has mov-ed the vertical shafts and theswitch-tongues and slot switchlbars to the reverse position the weightwill then hold them in said position.

The rock-shaft C12 is operated in the following manner: The saidrock-shaft is provided with an arm D, as shown in Figs. 2 and 3, whichis connected to an arm D on a rockshaft D2 by a rod d. The rock-shaft D2is mounted in bearings d', secured to the side of the rails A. The saidshaft is also provided With an arm D3, having pivoted thereto a rod D4,which is pivoted at d2 to the lower end of the central operating-pin E,as shown in Figs. 3, 4, and 5. The pin E passes up through a disk F andis operated upon by the automatic switch controller carried by the car.Said switch-controller, which is not shown in thedrawings, may be of anyform, but preferably a block suspended from the car having a cam-surfacethe angle of which may be set so as to give the pin E a motion at rightangles to the tracks A and A' when the said cam is brought in contactwith the pin E by the moving car. The switch-controller is adapted to beset so as to move the pin E in either direction, the effect of whichbeing to open or close the switch. The motion received by the pin E iscommunicated to the rod D4. (Clearly shown in Fig. 3.) Said rod isconnected to the arm D3 on the rock-shaft D2, which is connected bythearln D', the rod d, and the arm D to the shaft C12. The rock-shaft C12communicates motion to the vertical shafts C and C through the mediumofthe level' C40, the lever C9, carried by said lever C40 and rods CTand CB, which are con nected to the said lever C9 and to the saidvertical shafts. The said vertical shafts'are each provided with armsC2, which are connected to the slot switch-bars by the links O4 and tothe switch-tongues by the links C2, thereby operating said switch-tongues and the slot switch-bars.

The disk F has a pin f, which is pivoted to the disk-frame F', held inthe projection F2 of the frame F3. The disk-frame F is provided with anopeningf, the ends of which act as a stop to limit the movement of thepin E. (See Fig. l.)

The pin E is provided with a head E', having arms E2, which enterelongated openings e in the levers E2 and E4. (Shown in Fig. 8.)

These levers are mounted upon a shaft E5, which is pivoted to the trackA', and a bar E( on the frame W. Said shaft E5 is provided with leversE7 and E8, having a connectingplate E9, upon which rests a pin E40,which projects up through an opening in the track A. This pin when actedupon by the carwheel depresses the levers E7 and ES and raises thelevers E3 and E4, which raise the pin E up above the surface of theplates B2, so that it may be engaged by the car. A spring G acts upon anarm g on the shaft E5 and tends to depress the levers E2 and E4,carrying the pin E. To hold the pin up against the action of saidspring, I provide an extension gon the lever E4, which is engaged, asshown in Figs. 4 and 5, by a projection g2 on an arm G2 on the shaft G3,pivoted in bearings in the track A' and the bar E6. An arm G4, Fig. 2,on said shaft is engaged by the spring G, which tends to hold the arm G2in engagement with the lever E4. A rod G5 is also pivoted to said armG4, and at its opposite end it is pivoted to an arm G*i of thebell-crank lever G7 on the shaft G8, which is mounted in a bearing g3 onthe track A. As shown in Fig. 9, the shaft G8 is provided with anotherarm G2,and between said arm and the arm G10 is a bar G14, supporting apin G12, projecting up through an opening in the track A', and is actedupon by the car-wheel, which depresses it, and, as shown in Fig. 4, thearm G2 is withdrawn from engagement with the iever E4, which is thenacted upon by the spring G, and the pin E is depressed.

The switch-tongues and the slot switchbars are also operated by the pinsH and I. As shown in Fig. 7, the pin H is pivoted at 71, to a lever Jupon the shaft J. The pin I is also pivoted to the said lever J at i.The said pins project up through openings in the rails and are engagedby the wheels of the car. The shaft J' is mounted in bearings J2, Figs.2 and 6, and is provided with an arm J4, which is connected by a rod J5to an arm J6 on the rock-shaft C42. It will be seen that a movement ofeither of the pins H or l will operate the said rock-shaft C12 and theswitchtongues A4 and the slot switch-bars B2 and B4. As shown in Fig. l,the plate B5 is provided with a pin BG, which acts as a stop and holdsthe slot switch-bars in their proper positions.

The operation of my invention is as follows: The car approaching theswitch from the left side of Fig. l depresses the pin E10 by the wheelpassing over said pin. This causes the operating-pin E to be raisedabove the surface of the plates B2. The automatic switch-controller uponthe car is then set so thatit will move the pin E and open the switch,so that the car may pass through in the desired direction. When thecar-wheel strikes the pin G42, the arm G2, supporting the operating-pinE, is withdrawn and said operating-pin is depressed, so the top of saidpin will be flush with the surface of plates B2. As the lOO IIO

mechanism is constructed so as to lock the switch-tongues and slotswitch-bars, a carreturning through the switch could not open thev same,as in the ordinary switch. Therefore the pins H and I are provided, andthe wheels of the car returning upon either the main track or the branchtrack A2 and A3 will contact with one of the said pins and operate theswitch, soas to open it and allow the car to pass through thesame.

Having thus described my invention, I claim and desire to secure byLetters Patent- l.
